The York and Lancaster Regiment was a line infantry regiment of the British Army that existed from 1881 until 1968. The regiment was created in the Childers Reforms of 1881 by the amalgamation of the 65th (2nd Yorkshire, North Riding) Regiment of Foot and the 84th (York and Lancaster) Regiment of Foot. The regiment saw service in many small conflicts and both World War I and World War II until 1968, when the regiment chose to be disbanded rather than amalgamated with another regiment, one of only two infantry regiments in the British Army to do so, with the other being the Cameronians (Scottish Rifles).
